Researchers in Denmark recently released a study saying one drink — and even up to moderate drinking (five to eight drinks a week) — might not do as much harm as we thought. (That’s according to a report from NPR.)

The researchers surveyed 1,600 pregnant women on their drinking habits, followed the development of their now 5-year-olds — and found no evidence to support that light to moderate drinking was harmful to the children’s development. (At the time of the study, Denmark hadn’t established that drinking while pregnant was a health risk.)

Studies about Fetal Alcohol Syndrome have shown that drinking while pregnant can lead to facial abnormalities, damage to the central nervous system, and cognitive impairments, to name a few. Other studies haven’t determined what amount of alcohol is acceptable to drink while pregnant, so doctors have always cautiously told pregnant women not to drink at all.

Of course, severe questioning to the Denmark study is still warranted: How the researchers chose and found their participants, and whether toddler age is too early to tell if there’s been cognitive damage are both legitimate questions that come to mind right off the bat.

For me, it is much more difficult to determine a “light to moderate” drinking habit than to lay off completely. In the end, the real question mothers should be asking themselves is whether drinking is worth the risk.
